Named after a fella called Bill. Who lives here :-

(South Coast of England)

Also known as the Breton Plotter (might be a few minor differences?) named after the North Coast of France.

My guess is that either family involved or the Plotter suits similar seas - short and lumpy, not ideal for parralel rules on small boats.

I've used versions of these for years: Chart Protractor #255. Simple, fast, accurate, works on chartlets in books or a folded chart on your knees and reads in True and Mag anywhere on the chart. What more could you want? No affiliation with the link I just googled it to find a picture.

Used in in New Cal on the French charts too. Worked great. Jim should get one
